This plugin makes things a little easier for network administrators managing their network plugins.

How so? Glad you asked! Active network plugins are separated from inactive ones on the WordPress network plugins page.

Need a visual? Check out this screenshot.

For WP 3.1+, if you're on a regular admin plugins page, you'll see a small blurb with an easy, direct link to your network plugins page.

If you're not using network mode, you don't need this plugin.
